hi all,

In my one of application a jsp invokes a sevlet do some calculations and saves data to db and at last redirect to same jsp from where request come from. flow is as simple as i explained but problem is that when two different client users click submit button then after servlet jsp page shows mixed data means user 1 gets data of user 2 not all page data but some textboxes.
where should be problem?

problem detail:
-mixing fields data stored in database in xml format at runtime it parses and assigns to particular field.
-i cant use ajax instead of servlet submit because there are lots of parameters which servlet requires.
-i have used synchronization in servlet and jsp. (don't know where it was required or not just tested!)

hope you are not having instance variables in your servlet and only using local variables

hello joy,

i have not any instance variable in servlet. and data saves properly in database but jsp retrieves/ shows data from other user.

I agree. Here's the link:
